Letters Patent No. 109,525, Ydated November 22, 1870. v

The Schedule referred to in these Letters Patent and meldngpart of the same.

To all whom fit may concern:

Be it known that I, JOSEPH LIcHTaNsrErN, of the city and county of Baltimore, in the State of Maryland, have made certain new and useful ImprovefY ments in Imbricators for Journals of Gar-Axles; and I do hereby declare thcfollowing to be a full,- clear, and exact descrptiou'of the same, reference being had to the accompanying drawingforming part ofthis specifica-tion, in which- Figure 1 is a perspective view ot luy-improved lubricator;

Figure 2 is a transverse vertical section ofthe same in the line y y, fig. 3; and

Figure ,3 is ahorizontal section in the line xx, tig. 2. Similar letters of reference in the drawing denote corresponding parts. j

My invention has for its object to improve the construction' of lubricators for thejoumals of car axles, whereby the same are rendered more economical and efficient in use; and to this end v l It consists,-irst, in dividing the lubricator into two compartments by means of a transverse partition, one compartment being adapted 'to receive the capillary substance employedy to supply the lubricant to the journal of a car-axle, and the other'being left open and extending in front of the journal, thus affording means for supplying the lnbricator with oil, Ste., -and also for inspectionof the latter from time to time. The invention consists, further, in constructing the Alubricator-box with vertical openings for the passage of strips of capillary substance'. whereby the lubricant escaping from the journaLor lubrieator into the axlebox is returned to the journal and prevented from accumulating in the axle-box.

In the accompanying drawing- A is -the journal of a car-axle, and

B the axle-box. j

O is -the lubricator-box,supported withinthe axlebox, beneath the journal, by means of the bent springs D. rlhe lubrcator is' made in the form of a shallow rectangular box, having a concave top, and of sufficient area to till the axle-box B.

lhc top of the lubrieator is provided with a central longitudinal opening to receive the capillary substance or bloc-lt H, and transversely of the box, at or near its center, a partition, F, extends, dividing the former into two compartments, Gr and G', communicating with each other around the .ends of the partition.

, The block H of the capillary substance is -inserted in the compartment G, and is of suicient size to fill the openings inthe-top ofthe lubricator above Gr, and

extend to and in contact with the undersurface of the journal, asshown in fig. 1.

rlhe lubricator having been filled with the f lubricant, the latter is carried to the journal through the medium ot' the block H, by capillary attraction,I as will be readily understood. e

The lengt-h of the block H is equal or nearly so to the journal, but the lubricator-box projects to the `front of the latter, so that the compartment Gr shall be exposed to view for supplying the lubricant, 85o., and for inspection from time Io time.

The partition 'F does not extend at either end en'- t-rely across the box, but terminates in two passages,

I, which passvertically through :the lubricator from top to bottoni, l j

Through these passages are passed wicks or strips J of capillary substance, whose'lower ends enter the axle-box beneath the lubricator, and whose upper ends reach the journal of the. axle or upper surface of' the block H. j

Dy this construction-any lubricant which may acci# dentally escape into the axle-box is carried, by capil-y lary attraction, back to the journal, or atleast to thev upper surface ofthe lubricator. As the passages are completely inclosed `within the lubricator they have no 'communication with the interior of the latter, and consequently the lubricant cannot pass through them to the. axle-bok.

Inasmuch as vthe journals of' car-axles vary somc.

what inlength, the length of the vblock H must also vary to correspond thereto. To accommodate these differences the partition and passages must he arranged nearer to or further from the center of the lubricator, as will be readily understood, carebeing taken, however, that 'sutlcient space is left to. form sisting of the shallow rectangular box C,the partition F, passages I, block H, wicks J, and springs D, sub'-A stantially as herein shown and described.
